- Radiation and health
Radiation is the emission of energy as electromagnetic waves or moving subatomic particles Natural radiation comes from many naturally occurring radioactive materials found in soil, water, air and in the body Every day, people inhale and ingest forms of radiation from air, food and water
- Radiation - World Health Organization (WHO)
Ionizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha) Ionizing radiation can remove electrons from the atoms, i e they can ionize atoms In terms of natural radiation sources, there are more than 60 different naturally occurring radioactive materials present in the environment, with
- Ionizing radiation and health effects
WHO fact sheet on ionizing radiation, health effects and protective measures: includes key facts, definition, sources, type of exposure, health effects, nuclear emergencies, WHO response
- Radiation: Ionizing radiation - World Health Organization (WHO)
Ionizing radiation is radiation with enough energy that to remove tightly bound electrons from the orbit of an atom, causing that atom to become charged or ionized Here we are concerned with only one type of radiation, ionizing radiation, which occurs in two forms: waves or particles There are several forms of electromagnetic radiation, which differ only in frequency and wavelength: Longer
- Rayonnements ionisants et effets sur la santé
À mesure que les usages des rayonnements ionisants se multiplient, les dangers qu’ils peuvent comporter pour la santé, s’ils ne sont pas correctement utilisés ou confinés, augmentent
- Radiation: 5G mobile networks and health
5G, or fifth generation, is the latest wireless mobile phone technology, first widely deployed in 2019 5G is expected to increase performance and a wide range of new applications, including strengthening e-Health (telemedicine, remote surveillance, telesurgery)
- Radiation: Ultraviolet (UV) radiation
Everyone is exposed to UV radiation from the sun and an increasing number of people are exposed to artificial sources used in industry, commerce and recreation The sun is by far the strongest source of ultraviolet radiation in our environment Solar emissions include visible light, heat and ultraviolet (UV) radiation Just as visible light consists of different colours that become apparent in
- Radiation: The Chernobyl accident
Among those who survived radiation sickness, recovery took several years Many of them developed radiation-induced cataracts in the first few years after the accident Recent studies of the recovery operation workers indicate that opacities of the eye lens might result from radiation doses lower than previously expected (about 500 mSv)
